A seat system includes a seat having a seatback and a seat bottom extending in a seat-forward direction from the seatback. A seatbelt retractor is mounted to the seatback and an anchor is carried by the seat bottom and movable seat-rearward and seat-forward between a retracted position and an extended position. A seatbelt webbing extends from the seatbelt retractor and is attached to the anchor. An actuator is operatively coupled to the anchor to move the anchor between the retracted position and the extended position. A lock is operable to selectively retain the anchor in the retracted position.

A height adjuster of a seat belt for a vehicle may include a rail bracket configured to be fixedly mounted on a vehicle body so that rail grooves are formed to be continuously connected and the rail grooves are vertically disposed on the rail bracket, a slider configured to be coupled to the rail bracket and moving along a length direction of the rail bracket and having left and right surfaces provided with guide grooves so as to be fitted in edge portions of the rail bracket which are provided with the rail grooves, and a locking mechanism configured to be coupled to the slider so as to elastically slidably move and restrict a movement of the slider at a time of contacting the rail groove and release the restriction of the movement of the slider at a time of being separated from the rail groove.

A number of variations may include a product comprising: a pretensioner that moves from a first position to a second position, several with a with guide loop assembly comprising: a guide loop; a pretensioner, wherein the pretensioner is attached to the guide loop; and wherein the pretensioner moves a guide loop from a first position to a second position upon deployment. A number of variations may also include a slot in the pretensioner body through which motion is communicated to a seatbelt anchor or guide loop to move it from a first position to a second position.

At a present through anchor, a through-hole is formed in a core metal. Due thereto, at the core metal, there is no metal portion of the core metal at a portion MF that is furthest from an outer peripheral portion of the core metal and a supporting hole and an insert-through hole. Accordingly, because there is no need for a heat treatment such as quenching or the like at the furthest portion MF and a periphery thereof, dispersion in mechanical characteristics at respective regions of the core metal after a heat treatment can be made to be small.

A web position and attenuation apparatus includes an elastically deformable body having a first end and a second end opposite the first end, one of the first and second ends configured to be affixed to a frame of a movable vehicle, a web coupling member received on the elastically deformable body, the web coupling member movable relative to, and positionable along, the elastically deformable body, the web coupling member defining a web slot, and a flexible web extending through the web slot, the flexible web part of a restraint system to restrain an occupant of a vehicle seat mounted within the vehicle. The elastically deformable body is responsive to dynamic loads applied by the occupant through the flexible web to the web coupling member to absorb energy and attenuate tension in the flexible web via elastic deformation of the elastically deformable body.

Guidance to a vehicle occupant is directed to manual adjustment of a height of a D-ring mechanism of a safety belt. First data of the occupant is collected which is indicative of a target height for the D-ring mechanism. Second data is collected indicative of a current height of the D-ring mechanism. The target height and the current height are compared to generate an adjustment amount whenever their difference is greater than a predetermined threshold. Visual guidance is presented to the occupant on an HMI display panel wherein the visual guidance describes taking an particular action to achieve the manual height adjustment of the D-ring mechanism. A further visual instruction is presented to the occupant on the HMI display panel wherein the visual instruction identifies the adjustment amount.

A belt buckle power actuator for a vehicle seat assembly may include a seat belt buckle arm pivotally mounted adjacent to a vehicle seat. The actuator include a motor having a drive shaft drivingly connected to a drive gear. A driven gear is meshingly driven by the drive gear and is drivingly connected to a lead screw. A nut is threadedly engaged with the lead screw and drivingly connected to the seat belt buckle arm.

A safety belt lower anchorage front-back adjustment structure may have a bottom base and a seat frame that is mounted on the bottom base. A support base may be respectively mounted on the bottom base at positions corresponding to a left side and a right side of the seat frame. A sliding component may be provided on each the support base. Two of the sliding components may be able to slide forward and backward on the corresponding support base. A driving assembly may be provided between the sliding component and the corresponding support base used for driving the sliding component to slide forward and backward among the two sliding components. A buckle may be fixedly mounted on one sliding component, and a lower anchor is fixedly mounted on the other sliding component.

A seat system includes a seat having a seatback and a seat bottom extending in a seat-forward direction from the seatback. A seatbelt retractor is mounted to the seatback and an anchor is carried by the seat bottom and movable seat-rearward and seat-forward between a retracted position and an extended position. A seatbelt webbing extends from the seatbelt retractor and is attached to the anchor. An actuator is operatively coupled to the anchor to move the anchor between the retracted position and the extended position. A lock is operable to selectively retain the anchor in the retracted position.

A center pillar's upper part trim includes a slider and a knob. The slider has a boss projecting in the back side direction. The knob has a flexible member extending in a cantilever manner in a first direction being one operation direction and other end opposed to the flexible member on the first direction side of the flexible member. The center pillar's upper part trim further includes: a slide-and-join structure allowing the knob to slide and join to a plurality of engaging catches from a state where the flexible member of the knob is placed on the boss; and a restriction structure restricting the knob, in a state where the knob has slid and joined, from excessively shifting in the first direction and the second direction by setting the boss between the flexible member and the other end when the knob is operated to slide.
